CROSS REFERENCE TO RELATED APPLICATION

This is a national stage application of PCT/EP2015/080051, filedinternationally on Dec. 16, 2015, which claims priority to FrenchApplication No. 1462631, filed on Dec. 17, 2014, which are incorporatedby reference herein in their entirety.

The present invention relates to a composition for dyeing keratin fibresusing a specific para-phenylenediamine oxidation base and a particularcoupler.

Many people have sought for a long time to modify the colour of theirhair and in particular to mask their grey hair.

One of the dyeing methods is “permanent” or oxidation dyeing, which usesdye compositions containing oxidation dye precursors, generally known asoxidation bases. These oxidation bases are colourless or weakly colouredcompounds, which, when combined with oxidizing products, may give riseto coloured compounds via a process of oxidative condensation.

It is also known that the shades obtained with these oxidation bases maybe varied by combining them with couplers or colouring modifiers, thelatter being chosen in particular from aromatic meta-diamines,meta-aminophenols, meta-diphenols and certain heterocyclic compoundssuch as indole compounds. The variety of the molecules used as oxidationbases and couplers allows a wide range of colours to be obtained.

Permanent dyeing processes thus consist in using, with the compositioncontaining the dye precursors, an aqueous composition comprising atleast one oxidizing agent, under alkaline pH conditions in the vastmajority of cases. The role of this oxidizing agent is to at leastpartly degrade the melanin of the hair, which, depending on the natureof the oxidizing agent present, leads to more or less pronouncedlightening of the fibres. The oxidizing agent used is generally hydrogenperoxide.

The basifying agent makes it possible to adjust the pH of thecomposition to an alkaline pH to enable activation of the oxidizingagent. In addition, this basifying agent causes swelling of the keratinfibre, with raising of the scales, which promotes the penetration of theoxidizing agent, and also of the dyes, if they are present, essentiallyoxidation dyes, into the fibre, and thus increases the efficacy of thedyeing or lightening reaction.

In the long term, the use of an oxidizing agent and an alkaline agentmay lead to degradation of the keratin fibres and also to inconvenienceat the time of use; in particular, ammonia may give rise toinconvenience to the user due to its strong characteristic odour.

Moreover, not only may the user be inconvenienced by the odour, but hemay also be confronted with greater risks of intolerance, for instanceirritation of the scalp, which is in particular reflected by stinging.

It is also important to obtain intense colouring, which is resistant toexternal factors such as light, shampoos and sweat, and which is asuniform as possible along the entire fibre, irrespective of the level ofdamage of the keratin fibre.

Oxidation bases of the para-phenylenediamine type are commonly used inthe field of hair dyeing. It is known practice, for example, to use3-(2,5-diaminophenyl)-1-propanol (or2-γ-hydroxypropyl-para-phenylenediamine) in oxidation dyeing, inparticular in document WO 80/00214. However, the dye compositionsobtained using this oxidation base are not always satisfactory inparticular for ensuring suitable coverage of grey hair with anacceptable colouring selectivity between the root and the end and/orsufficient fastness with respect to external attacking factors such aslight, shampoos, bad weather, etc.

One of the objects of the present invention is to propose compositionsfor dyeing human keratin fibres such as the hair, which have superiordyeing properties relative to the existing compositions.

In particular, the composition according to the invention in thepresence of a chemical oxidizing agent must make it possible to obtaincolours that are satisfactory, in particular in terms of power, but alsowith sufficient uniformity of the colour from the end to the root of thehair, which makes it possible to avoid a “root” effect of the colouring.Finally, it is also possible to obtain colourings that are very stabletowards external agents.

Furthermore, the invention makes it possible to achieve substantialdegrees of lightening while at the same time colouring, and does sowithout using oxidizing agents such as persalts or forcing the amount ofchemical oxidizing agent or of basifying agent.

Moreover, the composition of the invention makes it possible to obtainformulations that are less malodorous during their application to thehair or during their preparation.

These aims and others are achieved by the present invention, one subjectof which is thus a composition for dyeing keratin fibres, in particularhuman keratin fibres such as the hair, comprising:

At the time of use, each composition B′ and B″ is mixed with theoxidizing composition C of example 1 at a weight ratio of 1/1.

The resulting mixture are each applied on natural hair locks (BN), whichrepresents the hair root, and permed hair locks (BP), which representsthe hair tips, in an amount of 10 g of composition per 1 g of hair, andleft for 35 minutes at room temperature (25° C.).

Then the hair was rinsed with water, washed with the “Pro Classicsconcentrated” shampoo (L'Oréal Professionnel), diluted at 10%, anddried.

Selectivity Evaluation

The color of the hair was determined using the CIE L*a*b* system with aMinolta CM2006D spectrophotometer (illuminant D65, angle 10°, specularcomponent included) in the CIELab system.

According to this system, L* indicates the lightness of the color of thehair.

The chromaticity coordinates are expressed by the parameters a* and b*,a* indicating the axis of red/green shades and b* the axis ofyellow/blue shades.

The selectivity of the dyeing is measured by calculating the variationof ΔE according to the formula:ΔE=√{square root over ((L*−L _(o)*)²+(a*−a _(o)*)²+(b*−b _(o)*)²)}

In which L, a* and b* represent the values measured on mediumsensibilized hair and L0*, a0* and b0* represent the values measured onhighly sensibilized hair.

The selectivity is represented by the difference of color between thecolored natural hair and sensibilized hair: the more is the ΔE value,the more the difference of color between natural and sensibized hair isimportant, which is representative of the homogeneity of the colorationbetween the raw and the tips along the lock of hair.

The following results are obtained:

Hair type L* a* b* ΔE B′ + C BN 22.14 1.16 0.36 3.85 (invention) BP18.39 0.54 −0.24 B″ + C BN 26.24 2.18 2.04 5.94 (comparative) BP 20.641.28 0.28

The mixtures B′+C according to the invention provide less selectivecolorations (lower ΔE value) than the mixture of compositions B″+C(comparative): the difference between the raw and the tips is lower withB′+C than with B″+C: the coloration along the lock of hair is morehomogenous with B′+C.
